EMMER B. ARNOLD, OF L05 ANGELES, CALIFORNIA.

WAVE-FORCE-UTILIZING DEVICE.

. Application filed. October 1'7 1913.

Z '0 all whom it may concern:

Be it known that I, EMMER B. ARNOLD, a cit'zen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a certain new and useful lVave-Force-UtilizingDevice, of which the following is a specification.

My invention relates to a means for utilizing the force of waves, andcontemplates the provision of a simple and eflective means for forcingwater or compressing air.

This invention further contemplates certain improvements upon mycopending application which has matured into Patent No. 1,214,257 rantedJanuary 30, 1917, in that a more e cient operation, by means of asimplified construction, is produced.

The accompanying drawing illustrates the invention.

Figure 1, is a perspective view.

Fig. 2, is a vertical sectional view.

Fig. 3, is an enlarged sectional detail showing a means for holding thestructure in position; the section is taken on line 33, Fig. 2, lookingin the direction of the arrow.

Fig. 4, is a sectional view taken on line 44 Fig. 2 showing a fragmentof the top of the structure and a fragment of one of the walls, which isremovably fastened to the top.

Fig. 5, is a perspective'view of a slightly modified form.

Fig. 6, is a vertical sectional view showing the flexible fluidcompressing compartments, and

Fig. 7, is a fragmentary section taken on line 77, Fig. 6, showing oneof the hollow water or air receiving walls for the structure.

Referring to the drawing similar letters of reference, denoting similarparts, 1, designates a bottomless inclosure, comprising a top 2, havinga preferably upwardly flaring end 3, and walls 4, whose ends flareoutwardly as at 5, the walls being attached to the top 2, by bolts 4,whereby the same may be removed. The forward ends of said walls 4 may beprovided with chambers 4", for air or water, as required.

011 each wall 4, is a plate 6, provided with a trunnion 7, mounted in asuitable bearing in the nature of a box 8, which is adjustably mountedon a slide 9, embedded in a concrete or other solid foundation 10. A setscrew 11, serves to secure said box 8,in

position of adjustment. Said trunnion pivotally supports the rear end ofsaid structure to enable the front thereof to rise and fall with thewaves, where this is desired, or the entire structure may be allowed torise and fall with the waves by releasing the set screw 11, thus leavingthe box 8, free to move on the slide.

The top 2, of said structure is provided with elongated slots 12,through which extend posts 13, to which the structure 1, is arranged tobe made fast, preferably by plates 14, swiveled on the ends of screws15, mounted in angle irons 16, which are riveted to the top 2, of theinclosure. In the end of said screws 15, are levers 17 for operatingsaid screws to lock the inclosure on said posts 13, and hold the same ata determined level.

When the device is to be held in a rigid position for utilizing theforce of waves in calm weather and normal tides, the front of the deviceis locked by the screws 15, referred to and the box 8, pivotallysupporting the rear of the device is locked on the slide 9, by the setscrew 11. Where, however, an unusual rough sea or high tide is apt todamage a rigid structure, the locking means at the front may be opened,whereby the whole structure then pivots at the rear, the weight of thedevice being sufliciently resistant to the waves to cause water or airto be forced therethrough.

On the top 2, of said inclosure 1, is a chamber 18, provided on theinside with a bag 19, of flexible material, the bottom of said bagnormally resting on transverse bars 20. Said bag is supplied with airthrough pipe 20.

The rear of said inclosure comprises compartments 22, to which water orair may be supplied, through a pipe 23, to cause the same either to sinkto its lowest possible position, or to float, as may be necessaryaccording to conditions.

Extending at an angle from the top 2, of the inclosure, to the bottom ofthe forward end of the compartments 22, and directly under said chamber18, is a wall 24, provided with a plurality of valves 25, which openinwardly under the force of the waves and which prevent the escape ofthe water. The water entering through the valves under great force,causes a compression of the air bag 19, which materially assists afterthe impact of the waves in forcing the water through the outlet pipe 26,to a suitable point for subsequent usage. T he air bag 19, beingcompressed, offers a yielding resistance to the compressing water andcauses a more even flow of the water after the impact of the incomingwaves.

A pipe 27, preferably furnished with a valve 27, may serve to conductair to a suitable reservoir or place of use, simultaneously with theforcing of water through pipe 526 whi h is also provided with a checkvalve 26. if the air in the bag 19, is desired to be used, it may beallowed to escape through the pipe 18 having a check valve 18, in whichevent the air will be drawn into the bag through the pipe :20, having acheck valve 20, when the bag is returned to normal position, preferablyby springs 28, though the bag may of itself assume its normal position.under its own weight, where the springs are disconnected.

T he stru ture represented by Figs. 5, 6 and 7, comprises a bottomlessinclosure 1 having hollow side walls 29, for air or water, these wallsbeing ren'iovably fastened to the top 2 in any suitable manner. The rearof the inclosure comprises a bag 30, suitably supported therein andattached at one end to a vane 31, hingedly secured as shown at 31 to thebottom of the top 2. On said top 2 is a pipe 32, through which aircompressed in said bag 30 may es'ape, av valve 33, being provided toprevent ingress of the compressed air back to the bag. A valve 3%,normally held closed by a spring 35, is provided to permit of air beingdrawn into the bag when the pressure is relieved by the recession of thewaves. An auxiliary air chamber 36, may be provided on the top :2" ofthe inf-losure. into which chamber the air from the bag 30, may becompressed and forced out through pipe 37. having a check valve 37. Aslide valve 38, may be employed to partially or completely close theopening to said auxiliary chamber 36.

Hingedly atta hed as shown at 39 to the underside of the top 2 is aplurality of vanes 39, to which are atta'lied flexible bottomlesscompartments 40, held taut by suitable means, as by weights 41. Ea'hcompartment is provided with valves 4%, nor mally held closed by springs45, and with an outlet pipe 46, provided with. a check valve 46. Underthe force of the waves, the air in these compartments is highlycompressed, and the compartments have a wide latitude of movement tobring about the greatest compression of the air.

The incoming waves produce a swinging movement of the vanes 39 and 31,conse quently redu ing the area of the compartments formed therebv and,with the rising level of the water highly compressing the air.

which escapes through the outlet pipes 46 and On the recession of thewaves the air is drawn into the compartments through the openingsleading thereto and normally closed by valves &4 and 34.

What I claim, is

1. A wave force utilizing device comprising an inclosure pivotallysupported at its rear end, an air chamber on said inclosure providedwith a pipe to supply air thereto, and having an outlet, a wall belowsaid chamber provided with a plurality of valves adapted to admit waterto and confine wa for within said chamber, and means to ad justablysupport the forward end. of said inclosure.

2. A wave force utilizing device comprising an inclosure, a pivotalsupport for the rear of said inclosure, a slidable bearing for saidsupport, means to support the front end of said inclosure, a chamber on.said inclosure, a container therein for a suitable fluid, and a supplypipe on said chamber for said container.

8. A wave force utilizing device comprising an inclosure having acompression chamber, a flexible bag in said chamber, a pipe to supplyair to said chamber, an outlet on said chamber, an inclined wall on saidinclosure having a plurality of valves arranged to be opened by incomingwaves and confine water in said chamber, and a water outlet on saidchamber.

4. A wave force utilizing device comprising an inclosure having aninclined wall dividing said inclosure into a wave receiving and a waterconfining chamber, a plurality of valves on said wall arranged to beopened incoming waves and confine water in said chamber, an outlet onsaid confining chamher, a compressible bag in said chamber, an airsupply pipe for said bag, and a valve controlled air outlet for saidbag.
